Players are able to go AFK for any length of time and avoid abandon so long as they receive XP.

There are times where maybe a player is in the trees for a minute setting up a gank, or in the base for a minute answering the door, or something. That's one thing. But ten minutes doing nothing? Twenty minutes? Longer? This shouldn't be possible.

Our carry player (Riki) sat without moving or doing anything in mid lane for 30 minutes or longer. We played most of the match without him. No abandon. They came back after an hour of the match without saying anything. Didn't apologise or explain it.

If players don't use abilities at all in some length of time they should get an abandon, regardless of if they are soaking up passive xp.
